WEEDER.

Specification of Letters Patent.

Patented dan. 29, 191%.

Application filed June 28, 1916. Serial No. 106,345.

To all 'whom it may concern.'

Ee it known that l, zen of the United States, and a resident of Havre,in the county of Hill and State of hfiontana, have invented` a new andImproved Weeder, of which the following is a full, clear, and eXactdescription.

The invention `relates to weeders and has for its object to so mount theknives that they can be set to or cut in ahorizontal plane or at anglesthereto.

A further object of the invention is to mount the knives so that theywill move to one side when they come in contact with an immovable objectand when the object is passed will be returned to normal posi` tion.

A practical embodiment is shown in the accompanying drawing forming apart of this specification and in which similar characters of referenceindi cate corresponding parts in all of the views.

F igure 1 is a perspective view of the improvement,

Fig'. 2 is a detail view ofthe standard and blade partly in section,

Fig. 3 is a perspective view of a modificaof the invention Ition andFig. 4 is a longitudinal section of the same with the knife standardremoved.

eferring' to F igs. 1 and 2, 5 is a beam of the frame of a weeder, inwhich the knives are mounted. A sleeve 6 mounted in the beam 5 isprovided at its upper end with a disk 7 and in said sleeve is mountedthe tubular-shaft 8.

In the lower end of the tubular shaft 8, the square upper end of thestandard 9 is adjustably secured by the set screw 10 and to the lowerend of the standard the knife 11 is secured. The knife 11 is providedwith a shank 12 which terminates in an arc-shaped member 13 providedwith a curved slot 14:. The member 13 of the shank of the knife litsinto the curved face of a block l5, whose other` face is roughened tolit against the roughened surfaces of the lower end of the standard 9,and a bolt 16 passes through the slot of the shank of the knife, theblock and Standard- By hUS f56- curing the knife tothe standard thelmlfe HENRY Hanns, a cit-V can be adjusted to cut in a horizontal planeor at angles thereto.

Upon the upper end of the sleeve 6, below the disk 7 thereof, is thedisk 17 and a bolt 18 passes through the hub of the disk and the sleeve6 into the tubular shaft 8. A coil spring 19 on the sleeve has one endsecured to the beam 5 and the other end to the bolt 18. The disk 7 isprovided with a plurality of openings 7 and the disk 17 with an openingl17, and through said openings a pin 2O passes. By this construction theknife will turn to one meets an obstruction and will return to normalposition after the obstruction is passed. To increase the tension of thespring the bolt 18 and 17 rotated to the desired extent, after which thebolt and pin are again replaced.

ln F ig's. 3 and el the construction is the same as that shown in Figs.1 and 2 with the exception that instead of a tubular shaft, in which theknife standard is mounted, a Solid shaft 21 having` a socket 9.1a at itslower end to receive the knife standard is employed. By my means can bereadily different angles of mounting` the knife, it and quickly set tocut at and will readily yield when meetingan obstruction, therebypreventing breakage. )ely means is also very simple and cheap.

`What I claim is:

hln an agricultural implement, a frame,v a shaft mounted to turn in. theframe, a spring` connected with the upper end of the said shaft. astandard vertically adjustable in the shaft, a substantially horizontalblade provided with a. vertical shank at one end, and means for adjustably securing' the shank to the lower end of the standard, wherebythe blade may be set to cut in a horizontal plane or at angles thereto.

2. ln an agricultural implement, a frame, a tubular shaft mounted toturn in the frame, an adjustable spring device connected with the upperend of the shaft, a standard vertically adjustable in the shaft, asubstantially horizontal blade provided with a vertical shank at one endand means for adjustably securing the shank of the side whenever it pin2O are removed and the diskV knife to the standard to set the blade at vdifferent angles.

f a spring connected With the said shaft, a

standard vertically adjustable in the shaft, a. substantially horizontalblade 'provided with a vertical shank having an enlarged and aro-shapedupper end provided With a the shank of blade and having an are-shapedface with which the enlarged arc-shaped end of the shank enga-ges, and abolt passing through the standard, block and slot of the shank of theblade.
